Borrowed from Persian دفتر‎ (daftar), meaning "register", "account book" or "notebook", ultimately from Ancient Greek διφθέρᾱ (diphthérā, “parchment”). There is also an irregular spelling with གཏེར (deb gter) based on a Tibetan 'folk etymology' connecting it to the meaning "treasure", due to the accidental similarity of the Persian-Greek -tar/-thérā with the Tibetan word. Thus it appears that this Greco-Persian etymology is also the ultimate origin of deb, the main Tibetan word for "book", as the monosyllabic deb is derived from the longer word deb ther.
